Abstract
The utility model discloses a bituminous mixture water stability wheel grinds test device, its characterized in that: including test container, guide rail, load wheel and rubber suction cups, be provided with fixing device in the test container, the last test piece that is fixed with of fixing device, the counter weight device has been placed to guide rail center top, the guide rail below is connected with the load wheel, the load wheel is connected with the rubber suction cups all around, rubber suction cups lug connection is to the test piece upper surface. The utility model discloses the load wheel that will be connected with the rubber suction cups comes and goes the walking on the guide rail, roll the bituminous mixture test piece, truly simulates bituminous paving moisture motion state, and the water stability that detects sum check bituminous mixture can, simple structure does not adopt complicated mechanism or complicated components and parts, this device comprises several simple components, and easy operation is convenient, and the practicality is strong.
Description
Technical field
The utility model relates to a kind of stability of asphalt mixture rolling test unit, is specifically related to a kind of rolling test unit of stability of asphalt mixture.
Background technology
Asphalt is a kind of compound substance, and primarily of pitch, coarse aggregate, fine aggregate, inserts composition, what have also adds polymkeric substance and lignose; Be mixed to form different structures by the material of these different qualities and quantity, and there is different mechanical properties.Water Damage on Asphalt Pavement mechanism is: under the flowing pressure effect of vehicular load, water enters asphalt inside, form pump and inhale effect, asphalt is moved in circles and washes away, cause compound cohesion to decline and lose and final stripping, show as purt slurry, loose, the hole failure mode such as groove, check crack.
Existing for check stability of asphalt mixture can have immersion Marshall test and indirect tensile test on frozen-thaw.Immersion Marshall test process load is dead load, can not simulate mechanical erosion that moisture produces asphalt membrane and repeatedly inhale pressure effect, the embedded squeezing power between what stability value reflected mainly gather materials, and for pitch and between gathering materials adhesion insensitive.Indirect tensile test on frozen-thaw adopts the two-sided compound test specimen hitting real 50 times, and voidage is comparatively large, and water is comparatively serious to compound internal corrosion, and therefore test condition is harsher than immersion Marshall test.Cleaving process can partly weigh compound tensile strength, also slightly reasonable than immersion Marshall test.But still there is certain defect: one is test specimen pre-service aspect, and the state of saturation due to test specimen depends on voidage and soaking time, and it is very difficult for making all test specimens reach water suction state of saturation at the appointed time; Two is the stressed aspects of test specimen, and load is dead load, the embedded squeezing power between what cleavage strength value reflected mainly gather materials and non-bituminous and the adhesion gathered materials.Two kinds of test methods all can not the real processes of simulated roadway Moisture Damage.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of stability of asphalt mixture rolling test unit.
For realizing this technical purpose, scheme of the present utility model is: a kind of stability of asphalt mixture rolling test unit, it comprises test container, guide rail, loadwheel and rubber suction cups, stationary installation is provided with in described test container, described stationary installation is fixed with test specimen, above described guideway centreline, is placed with counter weight device, below described guide rail, be connected with loadwheel, described loadwheel surrounding is connected with rubber suction cups, and described rubber suction cups is directly connected to test specimen upper surface.
As preferably, described test container is cisten mechanism, and described test container is with temperature regulating device.
As preferably, described loadwheel is rubber wheel or steel wheel.
As preferably, the rubber suction cups on described loadwheel is one or more.
The beneficial effects of the utility model, go and back running the loadwheel being connected with rubber suction cups, roll bitumen mixture specimen on guide rail, real simulation bituminous pavement moisture movement state, detect and check the water stabilizing of asphalt; Structure is simple, does not adopt complex mechanism or complicated components and parts; This device is made up of several simple component, simple to operation, practical.

Described test container 7 is cisten mechanism, and described test container, with temperature regulating device, can test the impact of different water temperature on test specimen.
Test specimen 5 is fixed in stationary installation 6, water is held in water tank 7, test specimen is made to be fully immersed in water, by immediately below loadwheel 3 or surrounding connect upper rubber suction cups 4, rubber suction cups 4 is just to test specimen 5, guide rail 2 is connected with above loadwheel 3, counter weight device 1 is applied on walking guide rail 2, the loadwheel 3 being connected with rubber suction cups 4 is gone and back running on guide rail 2, bitumen mixture specimen 5 is rolled, rubber suction cups 4 direct effect bitumen mixture specimen 5, realizes pumping into and pumping of moisture under rolling effect, real simulation bituminous pavement moisture movement state.
Described loadwheel 3 can be rubber wheel or steel wheel, and rubber suction cups 4 quantity on described loadwheel 3 can be one or more.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
